50 MHz To 2 GHz Quadrature Demodulator

The ADL5387 is a Broadband quadrature I/Q Demodulator that covers an RF/IF input frequency range from 50 MHz to 2 GHz. With a NF = 13.2 dB, IP1dB = 12.7 dBm, and IIP3 = 32 dBm @ 450 MHz, the ADL5387 Demodulator offers outstanding dynamic range suitable for the demanding infrastructure direct-conversion requirements. The differential RF/IF inputs provide a well-behaved Broadband input impedance of 50 and are best driven from a 1:1 balun for optimum performance.
Ultrabroadband operation is achieved with a divide-by-2 method for local Oscillator (LO) quadrature generation. Over a wide range of LO levels, excellent demodulation accuracy is achieved with amplitude and phase balances ~0.05 dB and ~0.4, respectively. The demodulated in-phase (I) and quadrature (Q) differential outputs are fully buffered and provide a voltage conversion gain of >4 dB. The buffered baseband outputs are capable of driving a 2 V p-p differential signal into 200 .
The fully balanced design minimizes effects from second-order distortion. The leakage from the LO port to the RF port is <70 dBc. Differential dc-offsets at the I and Q outputs are 60 dBm.
The ADL5387 operates off a single 4.75 V to 5.25 V supply. The supply current is adjustable with an external resistor from the BIAS pin to ground.
The ADL5387 is fabricated using the Analog Devices, Inc. advanced silicon-germanium bipolar process and is available in a 24-lead exposed paddle LFCSP.
